This invention relatesto' door operating devices and has particular reference to an automatic head door for automobiles of the 7 closed type.

The principal object of theinvention rezsidesrin a'doo-radapted tob'e' arranged in the top fofa body of-an automobile adjacent the side door and-- which top-door is auto matically operated upon the actuation of the side door to provide amplehead -room'ior persons entering and lea ing the interior of the automobile; 1

Another object is as p vieea ammasc top door for motor vehicles which allows ample head room at the entrance and exit of the .same,'and which excludes the weather from the interior of the vehicle when the door is in an open position.

I I the automobile.

A further object isto" provide an automatic head door for automobiles wliioh is simple in construction and which does-not detract fromthe attractive "appearance, of

With these and other objects in view,the

invention resides in certain novel construction'and combination and arrangement of parts, the essential features of which are hereinafter fully described, are particularly pointedout in the appended elaims, and are illustrated in Which:'- V a Figure 1 is a perspective view of a portion of the body of an automobile with my 1 invention installed therein.

Figure 2 is a transverse sectional view on the line 22 of Figure l. i Figures 3, 4L and 5 are detail views of the several modifications of my invention.

Referring more particularly to the draw ings, and especially to Figures 1 and 2, the

reference numeral 10 designates a portion of the body ofan automobile of the closed type havingihingedly mounted side doors 11 for closing the entrance and exit openings 7 12. The top 13 of'the bodyis provided with head openings 14 in alignmentfwith the} openings '12 and are closed by the top doors 15. Thetop doors are hinged tothe top 7 13 asat 16 and when closed, the same co-act with the doors 11 to -provide an enclosed In order to actuate the top door 15 on each side of the body simultaneously with its respective side door. there is provided an in-- dividual top door actuating mechanism 17,

m'aining ilar' ball and socket joint 23.

the accompanying drawmggin' Applieati onfiled my 1; 19,25. senziliiv'o. 27,321.

Each mechanism includes a lazy-tong 18, the links atone end being pivoted on common point to one side of the top door as at 19, while oneof the links at the other end 7 ispivotedto the top 13 as at- ZOL ,operating arm 211m one end secured tothe inside'of the side door by meansfof; a ball en'dflink of the 1laz-y-tongby a collapsed as "shown at therightin Figure .2 of "the drawing but as the side door 12' is moved outward aboutits hinge, the same will move the arm 21 causing a pull to'lbe ex erted upon the lazy-tong" thereby extending the same which moves the top door about its and socket connection 22, while theothe'r 7 ends of the arm is 'connecte'dJWit-h the re o In practice, the lazy-tong-18 is normally hinge" to a position shown at the left in Figu're'2. The universal connections be- '-tween the door 11 and the arm, and between the; arm andthe lazy-tong allows the arm to swingon anaro when the side door-is opened without causing the parts to jam.

The weight of the door when swinging to "an open position beyond willsupport the top door in an open position. Asthe side door is closed, the top door is simultane ouslymoved to a closed positionja's wiilgbe readily understood. 7

To prevent the elements "of the weatherfrom entering the interior of the body when the top door is elevated, I provide flexible From the foregoing description, it will be readily appreciated that persons may enter and leave the interior ofan automobile Without fear 7 the top.

of strikingtheir-heads against InFigure 3 Of the drawing, I have' shovvn a slightly modified form which includes a gear segment 25 secured to the top of the door lliand having its axis in alignment with the pivot of the door. A gear 26 is 'mounted in the top door 27 and meshes with the gear segment. It will be seen that as the side door 11 is moved about its pivot,

motion will be transmitted to the topdoor through the segment 25 and gear 26 in raising and loweringv the same. A suitable folding weather screen 28 is also provided for excluding the elements. 7

In Figure a of the drawings there is shown a further modification which is somewhat similar to the form shown in Figure 3, but in this form I provide a pair of top doors 29 which are simultaneously operated by the movement of the side door. A segment 30 is mounted on the top of the side door and is similar to the segment 25 shown in the above form which meshes with a'gear 31 keyed to the end of the shaft 32 which carries one of the door sections 29. A gear 33 is keyed to the other end of the shaft 32 and co-acts with a'gear 34 on the end of the shaft'35 mounted at right angle to the axis of the shaft 32. The other end of the shaft 35 supports a gear 36 for mesh with a similar gear 37 secured to the, other door section 29. It will therefore be seen that motion will be transmitted from the side door to bothof the top door sections for simultaneous operation. A flexible weather strip 38 is attached to the meeting ends of the door sections for closing the space therebetween when the doors are in an open position.

In Figure 5, I have shown a still further modification which is somewhat similar to the preferred form of my invention but in which the lazy-tongstructure is dispensed with. In this form, a. tail or lever 39 extends beyond the pivot of the top door 40 and is connected by a ball and socket joint 41 to one end of an arm 42, the other end of the arm being connected to the side door by a ball and socket joint 43. As the side door moves to an open position, the arm 42 will pull the tail of the top, door thereby swinging the same about its pivot. The opof the other end is'secured to a stat parting from the spi it of my invention, and

I therefore do not llmlt myself to the enact details of construction herein set forth nor to anything lesstlian the whole of my vention limited only by the appended claims. What is claimed as-n w is: 1. In combination with 'a pair of swing ingly mounted closure members having their axes of rotation disposed at right angle to each other, a lazy-tong having one pair of its end links connected with one of said closure members, while one of the end links y structure and the other end link operatively connected with the other closure member, whereby movement of last m ntioned closure member will be correspondingly transmitted to said other closure member."

2. In combination with a pair of sur ingly mounted closure members having their axes of rotation disposed at right angles to each other, a lazy-tong having one pair of .its end links connected with one of said closure members, while one of the end links of the other end is secured to a stationary structure and the other end link operatively connected with the other closure memberby a rod'having universa movement with said end link and said closure member whereby movement of said last mentioned closure member will be correspondingly transmitted to sald other closure member.
